    hi... did u Check  out the fuel injectors first by buying the cleaning product. then check for vacuum leaks around the Fuel injector housing. Buy some starting fluid and spraying it over the small hoses while the car is running will make the engine stall when the fumes from the starting fluid get into the system. then have it scanned again to more or less tell which sensor it is. it could very well work with the fuel injector...

    thank u

The vehicle will not start shortly after turning vehicle off. Needs to set 6-7 hours or overnight and then will restart. Restarting is the problem.

didnt specify vehicle -generic answer --check the fuel relay and fuse board -relay may be overheating or connections need cleaning also check the wiring and pump [amperage ]if pump is pulling high amps can cause same problem --check camshaft sensor may be going bad also new doesnt mean free from defects

I have a buick lesabre and it just quit running I have changed the fuel pump fuel filter spark plugs and wires and had the coil pack tested and they are good and the car will turn over but not start

didnt specify vehicle --generic answer --why did you change all those parts were they all bad ---square one check fuses and relays try to start with ether /starter fluid if starts fuel problem retest pump new doesn't mean free from defects also test relay and wire harness --if no start possible ignition switch wiring retest coils and plugs for spark ----with another person have them try to start vehicle while you feel back of exhaust if feels and sounds clogged possible bad catalytic converter---test and check egr valve possible carbon build up

I have a 2003 Buick lesabre which starts and runs but periodically it stalls while driving it sometimes starts back up some times doesn't but the mechanics can't figure out what's wrong with it I think it...

Well mike the mechanic you use must not be very good ! Did he test fuel pressure ? This has no fuel switch but there is a relay an it is turned on by the PCM - powertrain control module ! When it won't start you need to find out what is missing Spark or fuel an go from there ! I will send a link for a youtube video on how to test this ! You could also test the fuel pump circuit at the relay in the under hood fuse/ relay junction block ! With a volt ohm meter test the relay socket , Two pin's should have batt. + one should have ground an the other should show open . that is the one from the PCM .

most likely time for a fuel pump. will need to check pressure to confirm,. At least you verified its a fuel issue. Just make sure you didnt pop the fuel pump fuse and rotate the fuel pump relay with another to make sure the relay is not bad. When you turn the key on the relay should click.

1987 GMC sierra , no fuel pump power.

The inline fuel pump fuse on the passenger side firewall is good? Are you jumping it with 12 volts at the test lead or the fuse?

1996 mazda mx6 ls cranks but won't start

you may need to run a wire from a keyed ignition source that has power while cranking and running to the fuel pump relay and bypass the pcm to test wether it will run, if it runs put a more permanent wire in place.Not too sure what tests youve done but it seems that fuel is what your focusing on so a quick test is too spray engine start up the intake tube to see if the engine trys to run if it does it eliminates a lot of other potential reasons for a no start condition.Also try squeezing the fuel return line to see if the added pressure will try to make engine run.Could be time to replace fuel pump etc anyway let me know how it goes good luck with it
